T0 ALL PERSONS TO WHOM THESE vPRESENTS WAY COMEI: A I

vBe it known thatI, FRANCIS SfB'ABBITT, of Taunton, in the county ofBristol, and State of Massachusetts, have invented a new and useful orimproved Nozzlefor Hose-Pipe, Hydrants, Ste.; and I do hereby declarethe lsame to be fully described in the following speciiication, 'andrepresented inl the accompanying drawings, of

Figurel is a side view, and A Figure 2 a longitudinal section of anozzle constructed in accordance with my'in'vention.

Figure 3 4is aiside elevation ofthe screw-plug or valve.'

rI he object off'my invention-is to so construct the nozzle orfor thedischarge of -wateigthat, by asimple and effective means,

discharging-mouth ofa hose-pipe or her v thc ilowage of water may beeither entirely'.

' vchecked or the water be' caused to ilow out in a solid cylindricalform, or in divergent lines, forming spray, or in a hollow conc, whosebase maybe of greater or less diameter, as may be desirable, thusperforming the func tions ofthe two nozzles ordinarily used, viz, thesprinkler and the Lsolidlstream nozzle.

In the said drawings, A denotes the body portion ofthe nozzle, which isahollow tube',-ma ing bore to receive a tapering screw-plug or valve',B. formed in it to screw on or connect with a male yscrew lattached tothe hose-pipe or hydrant. body, and on opposite sides of the borethereof,.I form two long chambers C C., which MTC ODPGIMG-.I junctionwith Atwo ports b b formed in opposite sides of the screw-plug B, asshown in.g2. The said's'erewy de with a taper- The large end of the saidbody has a femaley iserewa With'aft plug has its upper end solid.Apassage, c, leads' from the ports l b', and axially toward and throughthe:

smaller end of -thciplug B. Furthermore, the said screw-plug'has itsfrusto-conical part formed-or ground, sof'- as to lit closely to theinterior surface-of the body A, and make a tight joint therewith. Thesaidplu'g :Baise` has a screw,.e, cut on its lower end to receive amilled nut, D, anda friction or checknut-,.E, which are arranged as seenin tig. 1. There is also formed on the periphery of the screw-plug atransverse recessor areal chamber j', the same being formed withshoulders orabutments g g', which areto operate withai'st'udftori"projecticnl, 7L,

formed on the inner surface of the bore ofthe' body A, asseen in iig. 4,which is an .end 'View of the said body',

The object of the said stud end chamber is to limit the rotary movementsof the Said screw-plug. A groove orl 4chamber,z', leads from thcchamherf across the threads ofthe screw, in manner as shown in iig. 3.@Theo of such groove is to enable the stud h to be vplaced in itschamber, and the screw-plug tob'e removedfro bodyportin whenever it maybe desirable.

Having described the construction of my improved nozzle, I will describeits operation. If we suppose the nozzle to be attached to a bose-pipecommunicating with a hydrant or rcser the voir of water,'., and wedesire to discharge thc water in a'i'ull and solid stream, we rst turnthe milled nut D, Yso as to bring-the two ports. b b into directcommunication with' the chambers C C of 'the-body A'. v Under thesecircumstances,

'the water will be discharged from the nozzle in` a streaml equal to thefull capacity of its bore. By turning-'fthe said nut a partialrcvolution,we can so limit the receiving-area of the ports b that thewater issuingfromthe H0221@ Will have thcfcrm of mist orspray, and, byay further movement'of the said nut D, the water may be caused to issueir'orth inl lines more or less divergent, forming ahollow cone o``greaterrol iess diamxqte'lr, as be desirable', and by a still fuathermovement ot' the nut D, the. ports b b may bo elosgd, d'Iug'rvflayjfhgAvw'agd of the water will be entirely checked. v i From the above it willbe seen-that, b

y the peculiar construction of my improved nozzle, it'scrves to per.form the duties of the two nozzles ordinarily employed,therebydispensing with the` cosi;l of one nozzle, and thc trouble ofchanging the nozzles, as circumstances may require.

I claim an improved hose-pipe nozzle', consisting of the body A, t

he hollowl screw-plug B, the milled nut D,

t hud the check-nut E, the whole being constructed arid made to operatetogether, substantially as above set forth- I also claim the screw-plugB, as madre withthechambermor recess f, the same operating inconjunctionwith the stud or projection tdispcsed Ourthe inner periphery' the bodyA, in thc manner and for' lthe purpose set forth.

FRANCIS S. BABBITT.
